Meta Analysis
The incidence of aspiration associated with the laryngeal mask airway: a meta-analysis of published literature.
To determine the incidence of pulmonary aspiration with the laryngeal mask airway (LMA). ⋯ The evidence to date suggests that the pulmonary aspiration with the LMA is uncommon and comparable to that for outpatient anesthesia with the face mask and tracheal tube. Meticulous attention to selection of low-risk patients and appropriate operative procedures and avoidance of light anesthesia should reduce the incidence even further.
